Multi-Series Line Chart with Interactions
This multi-series line chart visualizes daily average temperatures in New York, San Francisco, and Austin over one year, with data loaded from a TSV file via d3.tsv. The visualization uses d3.time.scale for the x-axis, d3.scale.linear for the y-axis, and d3.scale.category10 for color encoding of the three cities. Each city’s temperature trend is rendered as a separate line using d3.svg.line, with axes displayed via d3.svg.axis. The chart applies conventional margins and computes domains using d3.extent, d3.min, and d3.max.
AI-generated descriptionThis line chart is constructed from a TSV file storing the daily average temperatures of New York, San Francisco and Austin over the last year. The chart employs conventional margins and a number of D3 features:
- d3.tsv - load and parse data
- d3.time.format - parse dates
- d3.time.scale - x-position encoding
- d3.scale.linear - y-position encoding
- d3.scale.category10, a d3.scale.ordinal - color encoding
- d3.extent, d3.min and d3.max - compute domains
- d3.keys - compute column names
- d3.svg.axis - display axes
- d3.svg.line - display line shape
